无名，天地之始
The nameless is the beginning of the sky and earth.Dao de jing 1.

A Japanese painter was commissioned by an American to paint him a picture. The picture has been made. In its lower corner a little bird sat on the branch of a cherry tree. The whole upper part of the painting was empty. The American examined the image with an unhappy face, and he asked the painter to paint something else on it as well, for it looks so empty. The Japanese refused to do so. When he was called to account, he explained that if he painted all the surface, the bird would have no room to fly.
